Partial Hospitalization, also known as "PHP" or Day Treatment, is a kind of drug treatment center which is meant to treat substance abuse issues and mental health issues which might be co-occurring. In a PHP center, the person in treatment partakes in various rehab services and approaches in the daytime and then returns home in the night time. This is done anywhere from five to seven days per week, depending on the severity of the drug problem. Partial Hospitalization can be most effective for addicted persons in Crest Hill, Illinois who may not be able to afford long-term inpatient treatment, or who are unable to be apart from their home for extended periods of time. While in Day Treatment, treatment clients participate in typical treatment services for addiction problems while also overcoming psychological disorders which may deter them from staying sober once rehabilitation is complete.
